Which Insurance Pays After a Car Accident? Uninsured Motorist, PIP and MedPay
By @zanexyjs138
After a car crash, more than one insurance policy may apply. People usually think first of the at-fault driver's liability coverage, but personal injury protection (PIP), MedPay and uninsured motorist (UM) coverage can matter just as much. A car accident attorney will usually ask for the declarations page of every policy that might apply, because the coverage often decides how much of a loss can be paid.
How fault rules shape coverage
Most states require drivers to carry minimum liability insurance, which covers injuries and property damage the insured driver causes to others. State minimum limits can be low compared with the cost of a serious injury. In at-fault states, the injured person generally claims against the at-fault driver's insurer. Some states use a no-fault system, in which each driver's own PIP coverage pays medical expenses and some lost income regardless of fault. No-fault states may restrict lawsuits against the at-fault driver unless the injury meets a legal threshold.
How PIP and MedPay work
No-fault states require PIP, and a few other states do as well, and some others offer it as an option. Depending on the policy, it may cover medical bills, a share of lost wages and some household expenses. Medical payments coverage, often called MedPay, is a separate and usually smaller coverage. It pays medical expenses for the policyholder and passengers regardless of fault, up to the limit on the policy. A car crash lawyer will check whether these benefits require prompt notice or a written claim.
When the other driver has little or no insurance
Uninsured motorist (UM) coverage applies when the at-fault driver has no insurance, and in many states it also covers hit-and-run crashes. Underinsured motorist (UIM) coverage applies https://paxtonkhtw371.capitaljays.com/posts/police-reports-dashcam-video-and-car-accident-evidence-2 when the at-fault driver's limits are too low to cover the loss. Some states require UM coverage, while others allow it to be rejected in writing. Rules on stacking coverage from more than one vehicle or policy also vary. In some states, a policy held by a relative in the same household may provide UM coverage as well.
How a UM claim works
The UM claim goes to the injured person's own insurance company, yet in that claim the insurer stands in the shoes of the uninsured driver, so it may dispute fault and the amount of damages. Policies often require prompt notice of the claim, and a hit-and-run claim may require a timely police report. Some states require that the UM insurer be served with a copy of the lawsuit against the at-fault driver. A car accident attorney will check these requirements early, since a missed step can put coverage at risk.
Repairs and rentals
Collision coverage pays to repair or replace the policyholder's car regardless of fault, minus the deductible. The insurer may then seek repayment from the at-fault driver's insurer through subrogation, which can sometimes recover the deductible as well. Gap insurance and rental reimbursement are optional coverages that can matter after a total loss.
Health insurance and liens
Medicare, Medicaid or a health plan may pay medical bills first and later seek repayment from a settlement. A motor vehicle accident attorney usually resolves these liens before funds are distributed. Coverage rules vary by state and by policy, and this article is general information, not legal advice.
